Thoughts about Solo Q

I've been playing for 2 years now and i train, watch lcs games and watch pro streams everyday to try to improve myself as a player and my gameplay, but ever since i started playing i've been stuck on silver rank. I might not be the most skilled player in the world by far but i compensate that with game knowledge and macro knowledge of the game which i got by doing every single one of those things i mentioned. Most of the times i play in solo queue i manage to be stuck with only feeders or people tthat just have no game knowledge and i usually end up loosing but almost every time i duo queue i win the games which led to a conclusion: solo queue is completely dead. If someone wants to climb ranks he/she should just play duo with someone of trust that think is good and climb together. Usually when i play duo q with some of my friends that is silver too i manage to win and climb, but the when i play solo q i usually end up loosing because my team mates dont play safe against a bad match up or dont group on mid game which leads to 3v5 fights that get the win to the enemy team. I just think that solo q should be re-analyzed and Riot should make some changes to the match making, not only because people usually end up in unbalanced teams, having, for example, 2 good players teamed up with 3 very bad players, for that elo, but because in my opinion that is too the biggest reason why people are so toxic in low elos, since they realize their team is very unbalanced and they will most likely loose. Comment your thoughts below and if you can, some tips and advices to climb would be useful
